Transcranial Doppler Ultrasonography

Neurosurgery Clinics of North America, 1994
Transcranial Doppler ultrasonography is an extremely useful adjunct in neurosurgical intensive care. Continuous improvements in TCD equipment as well as computer software have improved examination success and also vessel identification. Recent expanding applications of TCD have also allowed the study of disorders of control of the cerebral circulation.

Transcranial Doppler and Transcranial Color Duplex in Defining Collateral Cerebral Blood Flow

Journal of Neuroimaging, 2018
In an acute stroke setting, transcranial Doppler (TCD) and transcranial color‐coded duplex (TCCD) have an important diagnostic utility in the monitoring of an arterial occlusion and microemboli detection.

Transcranial Doppler: state of the art

European Journal of Radiology, 1998
Transcranial color Doppler sonography permits the accurate assessment of intracranial arteries. The latest Doppler units, using the color and power techniques, can show even very small flow volumes (1 x 1 mm). Low frequency (2-2.5 MHz) and very focused transducers are used in transcranial color Doppler.

Advances in transcranial doppler ultrasonography

Current Neurology and Neuroscience Reports, 2008
Transcranial Doppler ultrasonography (TCD) is the only noninvasive real-time neuroimaging modality for the evaluation of characteristics of blood flow in basal intracerebral vessels that adds physiologic information to structural imaging. TCD has been rapidly evolving from a simple noninvasive diagnostic tool to an imaging modality with a broad ...

Transcranial Doppler Sonography

Archives of Neurology, 1994
Despitegrowing interest and a rapidly expanding literature, the clinical usefulness of transcranial Doppler sonography (TCD) has not been universally accepted. 1 Imaging modalities such as venous digital subtraction angiography and xenon 133 enjoyed similar initial enthusiasm only to be relegated to limited indications or abandoned because of ...

Transcranial Doppler in brain death

Neurology, 1987
Transcranial Doppler examinations (TCD) of 24 brain-dead adult patients demonstrated persistent movement of blood within the middle cerebral arteries in 21. The characteristic pattern of Doppler shift frequencies, seen in 14, was a sharply contoured, brief anterograde systolic envelope with reversed diastolic flow.

Transcranial Doppler in carotid endarterectomy

Journal of Clinical Neuroscience, 2001
To evaluate the role of transcranial Doppler monitoring in reducing the complications of carotid endarterectomy, by analysing: (1) perioperative intracerebral blood flow velocity; (2) embolic load; and (3) effect of Dextran-40 therapy on patient outcome.Retrospective case series.The study cohort consisted of 30 consecutive patients undergoing 32 ...
